Need some help on two codes:





P0441

Evap Purge Valve Incorrect Flow Fault




P1590

ABS rough road signal circut malfunction; Hardware is ok, but SLABS ECU is sending an error

 

Loose/bad gas cap.
Bad ABS sensor.
These codes have come up before and I am 90%, ok 80% that these are the problems.
I am sure that DiscoMike will chime in with a better and more accurate answer than me. Take his answer over mine.

 

I was thinking that but good to have more opinions, thanks

 

Because the EVAP system is a closed loop and the gas tank is part of that loop a loose/bad gas cap will set off emission codes.
And the SLABSECU is the second longest lasting part on your Rover, the check engine light bulb is the longest lasting part on any Rover.
